Exodus 7:18-20

Lexham English Bible

¹⁸ And the fish that are in the Nile will die, and the Nile will stink, and the Egyptians will be unable to drink water from the Nile.”’”

¹⁹ And Yahweh said to Moses, “Say to Aaron, ‘Take your staff and stretch your hand out over the waters of Egypt and over their rivers, over their canals, and over their pools and over all of their reservoirs of water, so that they become blood,’ and blood will be in all the land of Egypt and in vessels of wood and of stone.”

²⁰ And Moses and Aaron did so, as Yahweh had commanded, and he raised the staff and struck the water that was in the Nile before the eyes of Pharaoh and before the eyes of his servants, and all of the water that was in the Nile was changed to blood.
